The wind erodes the earth by moving pieces of it every which way.

Explanation:

Every patch of air carries hundreds of thousands pieces of dirt sand and chunks of earth. When the wind changes course it will slowly pick up more and more and until an indent will form. This is also how sand dunes are made.

If the wind constantly pushes a rock, eventually the sides will start eroding, and the wind will cause it to break and erode.

The blowing wind constantly changes the earths surface by moving rocks, and breaking them.

by the wind constantly pushing sand on top of each other in one place.

Explanation:

so since they all have the same shape? i mean maybe because m& m and reeses are both chocolates
